Augmented reality (AR) technology has transformed various aspects of life, including education. The following article will explore how AR affects our education style.
In today’s digital era, technology continues to develop rapidly, taking us in a more advanced and interesting direction. One increasingly popular technology is augmented reality (AR). AR is no longer just a dream from the world of science fiction but has become a reality that significantly changes how we interact with the world around us. Therefore, this article will explore how this exciting technology is used in learning.
What is Augmented Reality?
Augmented Reality (AR) is a technology that allows users to see virtual objects integrated into their real world. AR adds a digital layer to the physical environment in its simple concept, creating a hybrid experience that combines the real and virtual worlds. This creates the sensation that the virtual elements seem to exist in the real world. So to understand how augmented reality works, it is important to know its main components. There are several key elements involved in creating an immersive AR experience:
Hardware (Hardware)
Hardware is the physical component required to access and use AR technology. This could be a device such as a smartphone, tablet, smart glasses (such as Google Glass or Microsoft HoloLens), or another dedicated AR device. This hardware is equipped with sensors such as cameras, accelerometers, gyroscopes, and other components that allow the device to detect and interact with the surrounding environment.
Software (Software)
AR software comprises applications and computer programs that create, manage, and display virtual elements in a physical environment. This includes AR applications downloaded to users’ devices, as well as software development platforms used by developers to create AR experiences. This software typically leverages image recognition, position tracking, and 3D modeling technologies to produce immersive AR effects.
Displays
Display is a component that displays virtual objects to users in a real physical environment. This could be a device screen such as a smartphone or tablet, a projector for direct projection onto a physical surface, or smart glasses with an integrated display. AR displays must be able to display virtual objects clearly and realistically and maintain visual consistency in the context of a changing physical environment.
Types of Augmented Reality
Each augmented reality type has its advantages and disadvantages depending on the application and usage needs. Here are some of the most common types of AR including:
Marker-based AR
This type of AR uses markers or identifiers scanned by the device’s camera to place virtual objects in precise locations in the physical environment. This marker can be an image, QR code, or other sign recognized by the AR device. When the device recognizes a marker, a virtual object appears or is embedded above it. An example of this type of AR is an application allowing users to see 3D animation when pointing their cellphone camera at a poster or book with a special marker.
Markerless AR
In this type of AR, virtual objects are placed in a physical environment without special markers. These systems use technologies such as pattern recognition, object detection, or spatial mapping to locate virtual objects accurately. Markerless AR is often used in navigation applications, where information such as directions, business locations, or tourist information is displayed over real-world scenes without special markers.
Projection-based AR
This technology uses direct projection to display virtual objects onto a physical surface, such as a wall or table, without special devices such as cell phones or glasses. This projection can be carried out using a special projector or other device capable of accurately projecting an image onto a specified surface. Users can then interact with those virtual objects using their hands or other devices.
Superimposition-based AR
This type of AR involves placing virtual objects directly on top of physical objects in the real world. These virtual objects seem to interact with existing physical objects, creating a strong illusion of integration between the real and virtual worlds. This type of AR includes applications allowing users to view virtual furniture in their real space before purchasing.
Examples of Using Augmented Reality in Education
The use of AR in education increases student engagement and motivation and allows for more personalized and adaptive learning according to individual needs. So, with technology continuing to develop, opportunities to integrate AR into educational curricula and learning experiences are becoming more dynamic and enjoyable. The following is an example of its use:
Interactive Learning
AR is used to bring course material to life more interactively and engagingly. For example, in science lessons, students can use AR applications to view three-dimensional models of molecules or living organisms and learn their structures better than using pictures or text in textbooks.
Interactive Learning in Applied Subjects
In applied subjects such as graphic design, animation, or architectural drafting, AR can bring course material to life and allow students to practice their skills in real contexts. For example, in graphic design lessons, students can use AR applications to view 3D models of their designs in actual physical environments, allowing them to evaluate and refine their work more effectively.
Technical Skills Training
Vocational school students studying engineering or technology can use AR to deepen their understanding of technical concepts and practical skills. For example, in mechanical engineering lessons, students can use AR applications to learn and understand how complex machines work by viewing 3D simulations directly on their desks. They can learn machine components, workings, and assembly processes in a more interactive and engaging way.
If interested in program development, you can take the Coding Class at Gamelab Indonesia. Then, you can combine the program with AR technology, further increasing its benefits. Of course, you will also benefit from the program.
